| Short Description | Global transversely isotropic Earth model created by inverting a dataset of 2366 earthquakes using full-waveform inversion. 305 iterations were performed down to a period of 33 s resulting in a sharp global velocity model which does not contain any 3D imprints of a starting model. The starting model was the one-dimensional isotropic PREM model with a smooth 3D crustal model and an intermediate step can be found in the LOWE model. |

| Usage Notes | For visualization purposes, the model is available here in netCDF format. However, For running simulations we recommend downloading the HDF5 version of the model. That version can be obtained from ttps://cos.ethz.ch/models.html | ||
